IMO the fastest implementation paints everything to a bitmap, then masks the

Please prove with test cases which take into account both speed and
memory usage and are executed against my implementation and also
against whatever else proposed =)
Things in practice are much more complex then one might initially
imagine. My regions implementation is reused for several things:
1> Drawing clipping
2> Drawing complex objects like poligons, polybeziers, arbitrary regions
3> To clip mouse/touch events
Thanks, this finally answers my old question, what's the purpose of
regions in your model. My suggestion was about clipping regions only,
not about regions as paint objects.
